Results interpretation
- Display rounding: choose 0–2 decimals to match your use case (IDs, forms, or medical notes).
- Unit consistency: stick to one unit in a workflow to avoid transcription errors.
- Benchmarks: try the presets (e.g., 170–180 cm) to see typical ranges and compare your value.
How height conversion works
Formulas, steps, assumptions
Formulas: total inches = ft × 12 + in; cm = inches × 2.54 (exact); inches = cm ÷ 2.54.
Steps: Enter feet+inches or centimeters → pick rounding → optional presets → copy a link with your inputs.
Assumptions: International inch standard; rounding is for display only.
Limitations: Population “averages” vary by region and time; use presets as neutral benchmarks.
Use cases & examples
Example 1: 5 ft 10 in → 70 in → 177.8 cm (1 decimal → 177.8 cm).
Example 2: 170 cm → 66.929 in → 5 ft 6.9 in (0 decimals → 5 ft 7 in displayed).
Example 3: 6 ft 2 in → 74 in → 187.96 cm (2 decimals → 187.96 cm).
Height conversion — FAQ
What is the exact conversion from feet and inches to centimeters?
First convert to inches (ft × 12 + in), then multiply by 2.54 cm per inch. The constant is exact.
Can I enter only inches or only feet?
Yes. You can leave feet empty and enter inches, or enter feet and zero inches.
Why do results differ when I change rounding?
We compute with full precision and apply your rounding only for display. Changing the rounding updates the display value.
How do I share a result?
Use the “Copy link with inputs” button. It saves your entries in the URL so anyone can open the same configuration.
Is there a standard height average?
Averages vary by population and over time. Use the presets (e.g., 170–180 cm) as neutral benchmarks instead of fixed ‘averages.’
Do you support centimeters back to feet and inches?
Yes. Enter centimeters and we’ll split the result into feet and inches automatically.

We convert height with exact constants so measurements stay consistent across forms, research, and international contexts. Enter feet and inches or centimeters—results update instantly with your preferred rounding.
Choosing units for your workflow
Medical and scientific contexts often prefer centimeters for precision and easy math, while everyday conversation in some regions sticks to feet and inches. Our converter bridges both without ambiguity.
Avoiding transcription mistakes
When moving between systems, round only at the end, and keep one “source of truth” for official records. The copy-link button helps you share inputs without retyping.
